WINDOW-SASH HOLDER.

Application filed November 23,1927. Serial No. 235,142.

This invention relates to window sash hold ers and its principal object is toovercome the tendency for improperly balanced window sash to move up or down from any adjusted position. Another object is to prevent w1ndow sash from rattling.

It is well known that some times the sash weights for a window sash are too heavy or too light to properly balance the sash, with the result that if too heavy the sash weights tend to raise the window, particularly if the window sash has a reasonable amount of play in the frame, and if the sash weight is too light the sash tends to fall from any raised position. In accordance'with the present invention the sash is held in any position of adjustment in spite of any unbalanced condition of the sash. The invention consists in the novel featureshereinafter fully set forth and claimed.

The invention is clearly illustrated in accompanying drawing, in which:

the

Fig. 1 is a perspective View of a fragment of a window, showing a simple embodiment of the present invention applied thereto Fig.

2 is a vertical cross section taken through fragments of the upper and lower sash of the window and illustrating the device inconnection therewith and Fig. 3 is a perspective view of one of the devices alone.

Referring to said drawing, which illustrates one embodiment of the present invention, the reference character 4 designates a fragment of a window frame, 5 the upper sash and 6 the lower sash of a window. 7 designates a fragment of one of the sash cords,

which leads from the sash 6 over a sash pulley to a sash weight (not shown) as is wellunderstood. If the sash weights are too heavyfor either sash, that sash will tend to rise from any position of adjustment, and iftoo light the sash will tend to fall. To hold the sash in any position of adjustment against rising or fallin due to the improper balancing T provide a holder 8, for the sash,

thereof, which in the form illustrated, comprises a length of wire or rod (preferably. spring wire) bent into substantially U shape, one of the branches (designated by 9) having an the frame, thereby frictionally holding the eye 10 formed on its end and the other branch 11 being rounded as at 12. The U bend 13 provides a spring like effect between the two branches 9, 11 whereby their tendency is'to spread apart whenever drawn toward each other. If desired the branch 11 may be made considerably longer than the branch 9 and it may be flattened if desired in a plane transverse to the plane of the device. The eye 10 is adapted for the reception of a screw 14, nail or the like for securing the holder to the win dow frame. I

In use the holder is secured to the window stop or strip 15 of the frame by the screw 14 at a point adjacent the meeting ends of the sash, with the branch 11 of the holder in pressing engagement with the side rail 18 of the sash, as is clearly illustrated in Fig. 1. The tension of the holder is exerted in pressing the sash against the parting strip 16 of sash in any position of adjustment despite the fact that the sash may be overbalanced or underbalanced. Moreover the holder acts to prevent the sash from rattling in case there is considerable play between the sash and the window stop and parting strip.

The, holder lies flat against the window step or strip1-5 and occupies very little space and doesnot interfere with shade or other curtains. If weather strips are used the holder may be placed between the weather strip and window stop or strip 15.

The holder may be provided for the upper V sash as well as the lower one and in that case it is secured to the outer windowjstop 8 or strip 17 in pressingengagement with the outer side of a side of the upper sash (see Fig. 2) Insome cases it may be found desirable to employ a pair of holders for each sash, one being secured at each side of the wiilidow in pressing engagement with the sas 1. a

While the friction created by the holder is sufficient to hold the sash in any position of adjustment, it does not interfere, pe'rceptibly, i

with work of raising or lowering the sash, and being made of wlre its presence is scarceunskilled persons to a Window which inclicates an overbalanced or 'underbalanced condition of the sash.

I claim as new, and desire to secure by Let- 5 ters Patent:

As a new article of manufacture, a Window sash holder comprising a short length of resilient Wl'IG; bent into U shape, one branch being approximately one half the length of the other and formed With a screw receiving eye at its end whereby it is secured to a Window frame with the other branch of the U, in pressing engagement throughout the major portion'of its length With the side rail of a Window sash.
